CONVEYER SYSTEM.

SPECIFICATION forming part Of Letters Patent No. 741,447, dated October 13, 1903.

Application filed July 19, 1902. Serial No. 116,293. (No model-l 1'0 a whom it may concern.-

Be it known that I, HIRAM W. BLAISDELL, a citizen of the United States, residing at Yuma, in the county of Yuma and Territory of Arizona, have invented a new and useful onveyer System, of which the following is a specification.

This invention relates to a conveyor system ,and particularly to such a system wherein a main and auxiliary conveyor are employed; and some of the objects of the invention are to provide a conveyor system which will be simple and cheap in construction and at the same time positive and effective in operation.

Another object of the invention is to provide means whereby the auxiliary conveyor can be driven from the main conveyor.

It is also an object of this invention to provide a conveyor system wherein the main conveyor occupies a plane below that of the auxiliary conveyor Whereon it discharges.

Furthermore, an object of this invention is to provide anauxiliary conveyor so constructed as to be capable of discharging material at various elevations.

With these and other objects in view the invention consists, essentially, in the construction, combination, and arrangement of parts, substantially as more fully described in the following specification and illustrated in the accompanying drawings, forming part of this application, in which-- Figure 1 is an elevational view, partly in section, illustrating the auxiliary conveyor particularly. Fig. 2 is an enlarged detail View of the means for driving the auxiliary conveyor and showing portions of the main and auxiliary conveyor, and Fig. 3 is an other detail view of the driving mechanism.

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, and particularly to Fig. 1 thereof, the reference character 1 designates parallel timbers supported upon posts or beams 2 and constituting a portion of a supporting structure or framework, and upon the timbers 1 are securedtrack-rails 3, whereon travel wheels 4, movably supporting a platform 5 or traveling bridge, preferably over the set of curved rollers 12 upon the top of the trough 9, the rollers being curved or, segmental to impart a longitudinal curvature; to the upper loaded lead of the main conveyor in order to prevent the material carried thereby from falling off of the conveyor during the operation thereof, as will be readily understood.

Upon the traveling structure or platform 5 are mounted vertical parallel posts 13 and 14,

supporting a discharging pulley or roller 15,

over which the main conveyor 11 passes to discharge the material thereon upon the auxiliary conveyor 16 and from which discharge pulley or roller the main conveyor 11 passes down under a guide pulley or roller 17 into the plane occupied by the main portion of the main conveyor and upon the curved rollers 12, as will be readily understood.

Formed on or connected with the vertical parallel posts 13 and 14, is a hood or casing 18, constructed to receive and direct upon the auxiliary conveyor 16 the material discharged by the main con veyer in passing over the discharge-roller 15, substantially as shown in Figs. 1 and 2 of the drawings.

One or more braces 19 may be secured to the platform 5 and to the post 13, and additional braces 20 may be employed upon the opposite side of the platform, if found desirable in practice, and an upright or angle-iron 21 may be mounted adjacent to the post 14:,

carrying a sheave or roller 22, over which ing the auxiliary conveyer15, substantially as shown.

Mounted upon the platform 5 are bearings or brackets 30 and 31, wherein is journaled a shaft 32,-oarrying a roller 33 and also carrying a beveled gear-wheel 34, meshing with a similar gear-wheel 35 upon a vertical shaft mounted in an extension 36 of the bracket or bearing 31 and carrying another beveled gearwheel, 37, meshing with a beveled gear-wheel 38 upon a shaft 39, carrying the guide-roller 17, over which the main conveyer 11 passes, substantially as shown in Figs. 2 and 3 of the drawings.

The ladder or auxiliary-conveyer frame 29 is movably connected with the shaft 32 at one.

end and is provided at the other end with a discharge pulley or roller 40 and with pulleys or rollers 41, mounted on the under side of the ladder to support the empty or lower lead of the auxiliary conveyer, while sets of curved rollers or pulleys 42 support the upper or loaded lead of the auxiliary con veyer,which passes thereover, around the discharge-pulley 40, back over the pulleys or rollers 41, and finally around the tail pulley or roller 33, thus completing the circuit. By means of this construction it will be seen that the main conveyer 11, which can be driven in any suitable manner, (not shown,) is caused in its travel to drive the auxiliary conveyer, which can be accomplished in the manner illustrated and described or by means of any other equivalent mechanism.

The operation of the invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following explanation thereof. The material to be conveyed is deposited npon the major portion of the main conveyer, which is then passing over the curved pulleys or rollers 12, and is conveyed by said conveyer over said pulleys and up over the discharge-pulleys 15, which travels with and is carried by the bridge or traveling structure as it moves throughout the length of the main conveyer, elevating that portion thereof only which is adjacent to the traveling structure or bridge, and from the discharge pulley or roller 15 the material passes or is discharged into the hood or casing 18, which directs the same upon the auxiliary conveyer to be by the latter transported and discharged at any suitable point throughout the length of the main conveyer and at any suitable elevation by shortening or lengthening the rope or cable 23. From the dischargepulley 15 the main conveyer 11 passes down under the guiding-pulley l7 and back to the around an end pulley (not shown) and back over the pulleys 10 in the frame 9 to an end driving-pulley (not shown) in the usual manner.

An auxiliary conveyer which is capable of discharging at any elevation is particulariy desirable for removing waste matter, which is generally deposited in piles that soon become so high that the waste matter cannot be discharged thereon from a fixed elevation; but by means of this invention the point of discharge can be elevated as the pile of material increases in height by simply winding up the supporting rope or cable.

It is not desired to confine this invention to the specific construction, combination, and arrangement of parts herein shown and described, and the right is reserved to make all such changes in and modifications of the same as come within the spirit and scope of this invention.

I claim 1. A conveying system provided with a main conveyer and an auxiliary conveyer in a plane above said main conveyer and at right angles thereto and constructed to receive the material therefrom and to discharge the same at an elevation.

2. A conveying system provided with a main conveyer, a cross auxiliary conveyer in a plane above said main conveyer and receiving material therefrom and means for elevating said auxiliary conveyer to increase the height of the discharge thereof.

3. A conveying system provided with a main conveyer, a traveling auxiliary conveyer mounted across and above said main conveyer so as to discharge at an elevation the material deposited thereon by said conveyer.

4. A conveying system provided with a main conveyer, a superimposed traveling structure, an auxiliary conveyer mounted thereon and constructed to discharge at various elevations the material received from said main conveyer.

5. A conveying system provided with a main conveyer, a traveling structure thereabove, an auxiliary conveyer movably connected at one end to said structure and receiving the material from said main conveyer and means for elevating the free end of said auxiliary conveyer.

6. A conveying system provided with a main conveyer, means for elevating and returning the same to its normal position, an auxiliary conveyer constructed to discharge at various elevations and mechanism for driving said conveyers.

7. A conveying system provided with a main conveyer, a support, an auxiliary conveyer movably connected therewith and having a gear-wheel at said connection, means for elevating and again returning said main conveyer to its normal position,a secondgearwheel and gear-wheels engaging the first and second wheels so that the main conveyer drives the auxiliary conveyer.

8. A conveying system provided with a main conveyer having a gear and an auxiliary conveyer in a plane above the main c011- veyer and at right angles thereto and having a gear driven by the first gear.

9. A conveying system provided with a ICC IO structure and an auxiliary conveyer mounted at right angles thereto on a traveling structure and driven by said main conveyerm In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
